with all the talk about their irreconcilable political differences, we wanted to see if they shared any common ground. and we found some. for example, there seems to be a permanent majority in congress that's completely satisfied with the current state of campaign financing and congressional ethics, and members of both parties have institutionalized ways to skirt the rules. most americans believe it's against the law for congressmen and senators to profit personally from their political office, but it's an open secret in washington that that's not the case. as the saying goes, the real scandal in washington isn't what's illegal; it's what's legal. georgia senator saxby chambliss likes golf, so much so that he spent more than $100,000 the past two years entertaining at some of the finest courses in the world. new york congressman gregory meeks prefers football; he spent $35,000 on nfl games. all of this was paid for with

political contributions, all in the name of democracy. >> peter schweizer: i think campaign fundraising is increasingly not just about winning elections; it's a lifestyle subsidy. >> kroft: peter schweizer is an author and fellow at the hoover institution. for the past few years, he and a team of researchers have been investigating the way congressmen and senators have personally benefited from the hundreds of millions of dollars in political contributions that have poured into the system. i think most people have the impression that campaign funds cannot be used for personal expenses. is that true? >> schweizer: yes. regular campaign funds cannot, that's correct. but there are ways around it. like all things in washington, the devil is in the details, and loopholes are usually put in place for a reason. >> kroft: for example, when congress passed the ethics reform act of 1989, it plainly stated: "a member shall convert no campaign funds to personal use." but soon afterwards, congressional leaders quietly

invented something called leadership pacs-- political action committees-- that were not technically campaign funds, and thus exempt from the personal use prohibition. this is a loophole? >> trevor potter: right. that's correct. >> kroft: trevor potter is a former chairman of the federal election commission. he says it didn't take long for congressmen and senators to figure out the distinct advantages of having a leadership pac, with no restrictions. >> potter: since they weren't around when the ban on personal use was put into place, they're not covered by it. and they can be used for literally anything. >> kroft: over time, the leadership pacs that were created as a way for congressional leaders of both parties to raise money and distribute it to their members have evolved into something different. today, nearly every congressman and senator has a leadership pac, not just the leaders, and they are used to solicit contributions from friends and supporters in order to advance their political agendas, their careers, and in many cases, their lifestyle. it's like a political slush fund.

>> potter: that's exactly what it is; it's a political slush fund. over time, we've had them. they've been outlawed. they spring back in new guises, and this is the latest guise. >> kroft: potter says they are essentially personal political expense accounts, financed largely by lobbyists and special interest groups. leadership pacs are now the second largest political revenue stream for members of congress. >> schweizer: you can use them for babysitting, paying for babysitters. you can use them for paying for car service. you can use them for travel. nobody's really checking to see whether this is personal or legitimate business expense. >> kroft: back in 2006, north carolina senator and presidential candidate john edwards used his leadership pac to pay his mistress rielle hunter $114,000 to make a campaign video. and republican congressman ander crenshaw of florida spent $32,000 hosting a tour of california wineries for a group of contributors from the defense industry, which he has some oversight of.

>> schweizer: look, they're not having leadership pac meetings at the hampton inn down the road. they're going to the premier golfing and resorts in the united states and in... sometimes, around the world. and that's ostensibly where they're doing this leadership pac work. >> kroft: for example, democratic congressman robert andrews of new jersey used $16,000 from his leadership pac, the committee to strengthen america, to fly his family to scotland, ostensibly to attend the wedding of a friend that he was thinking about hiring as a political consultant. >> schweizer: why he needed to meet him in edinburgh, scotland, at a four-star resort, i think, is open to question. so they will categorize them as something related to the leadership pac. but in reality, they're for personal use. >> kroft: we wanted to talk to congressman andrews about his leadership pac and the family trip to scotland, but were turned down. we did manage to find him at a hearing, and passed him a note announcing our presence. andrews, it turns out, is under investigation by the house ethics committee for misusing

campaign funds to advance the career of his daughter. he agreed to talk to us outside. what about this trip to scotland? >> rob andrews: i follow all the rules, met the standards, and there is a matter pending before the house ethics committee. under those rules, my obligation's not to talk about the investigation until it's over. >> kroft: we talked to the ethics committee. they said they have no problem with you talking to us about this. >> andrews: well, it's my understanding of the rules are that, when there's a pending matter, i'm supposed to keep it confidential and so are they. so, i'm going to follow those rules. >> kroft: these leadership pacs have been described by a lot of people as sort of political slush funds. do you agree with that? >> andrews: you know, i think we should take a look at having clearer rules at what they can and cannot be spent for. i'd be for that. >> kroft: that's what almost everyone in congress says, but no one really seems to want reform. it should be pointed out that not all congressmen use the their pacs for their personal benefit, but the federal election commission has called the level of abuse substantial.

its former chairman, trevor potter, says the commission has consistently recommended to congress that it should outlaw the personal use of leadership pacs. and what's happened to that recommendation? >> potter: nothing. you know, it enters a black hole. >> kroft: that's because the leadership pacs have become a political annuity for congress that members can cash in when they leave office, or hold onto for the future. >> potter: what you see more often is that members will keep the leadership pac, and they will use it in retirement for everything that is vaguely a political expense. if they become a lobbyist, which about half of members who leave congress do nowadays, that becomes their lobbying slush fund. it just keeps going, at least until death. >> kroft: and even beyond death. >> potter: well, even beyond death, someone else is spending that money. >> kroft: when republican congressman paul gillmor of ohio died suddenly from a heart attack in 2007, his staff decided that no political contribution should go unspent. >> potter: the staff went off to

a number of dinners and pizza parties and other events using the leadership pac money. what they said was, "well, it's a grieving process. and also, we need to talk to each other about getting new jobs, and this is a way to do it." >> kroft: and nobody had any problems with that? >> potter: the problem is, it's not illegal. >> kroft: there are lots of things in washington that would seem to be illegal but really aren't, if you know your way through the loopholes. melanie sloan is the executive director of citizens for responsibility and ethics in washington, a small group that tracks campaign expenditures. as we said earlier it's against the law to use campaign funds for personal use, but sloan says it's perfectly acceptable to use campaign funds to hire your wife, husband, children, grandchildren, and in-laws. >> melanie sloan: while there are anti-nepotism rules that prevent them from hiring their family members on the official staff, they can indeed hire them on the campaign payroll, and do.

>> kroft: and they do? >> sloan: and they do. >> kroft: sloan says there are at least 75 members of congress who have hired members of their family to work on their campaign and paid them with political contributions. until republican congressman ron paul of texas retired last year, he seemed to be the leader with six family members on the campaign payroll-- daughter, daughter's mother-in-law, three grandchildren, and a grand child-in-law, paying them a total of $304,000 over the past two election cycles. but paul only ranked third in total pay-outs to family members, behind former republican congressman jerry lewis and democratic congresswoman maxine waters, both of california. for some congressmen and senators, this is sort of a family business. >> sloan: absolutely. it is a family business. they have members of their family on the campaign payroll. and they also will often have members of their family who are lobbyists and lobby on issues in which the member may even be working.

>> kroft: we were interested in talking to republican congressman rodney alexander, who had just retired midterm, after winning a campaign with no democratic opposition last year, a race in which he paid his two daughters a total of $130,000. congressman? steve kroft from "60 minutes." we just wanted to ask you about both your daughters on the campaign staff? i mean, the figures that we have according to the reports are $73,000 to lisa lowe, and $57,000 to ginger. >> rodney alexander: that's for a two-year... that's for the election cycle. >> kroft: what exactly did they do? can you tell me? >> alexander: do everything others do for other campaigns. >> kroft: whatever they did, it couldn't have been that stressful. alexander won 78% of the vote against a libertarian candidate who wanted to abolish the i.r.s. i mean, to some people, it just looks like you're using your campaign fund to enrich your family. >> alexander: well, somebody has to do that work, steve.

>> kroft: so, you kept it in the family? >> alexander: well, i kept it with somebody that i can trust and if one can't trust their daughter, then who can they trust? >> schweizer: i think it's the kind of nepotism that, in large parts of american society, we frown about. i mean, in corporate america, a lot of corporations have policies that relate to nepotism and the hiring and firing of individual people. but congress has created this domain that allows them to decide whether something is ethical or whether something is good. and it's another example, unfortunately, where the rules that apply to the rest of us don't really apply to members of congress. >> kroft: in january, senator david vitter of louisiana introduced a bill to try and rectify the situation. it would prohibit members from paying relatives with campaign or leadership accounts. >> david vitter: that is a loophole, an area of abuse that we must close. >> kroft: so far, senator vitter has not found a single co- sponsor.

and no one is the least bit surprised. >> sloan: everyone in washington knows this goes on. it's well-known, an open secret. the problem is people in ohio and new mexico have no idea what's going on here in washington. >> kroft: sloan says another way congressmen can personally benefit from the use of political contributions is by making personal loans to their campaign funds, then charging above-market and sometimes exorbitant interest rates. sloan's organization found at least 15 cases, with the worst offender being democratic congresswoman grace napolitano who charged her campaign 18%. how much money did she loan her campaign? >> sloan: she loaned herself $150,000, and over a 12-year period, took in $228,000 in interest. >> kroft: i think everybody would like that investment. >> sloan: i think so. >> kroft: and that's legal. >> sloan: and that's legal. >> kroft: after weeks of trying to get an interview with congresswoman napolitano, we finally cornered her outside a meeting of the hispanic caucus. she told us that as a woman and

a minority, banks wouldn't lend her money, so she had to withdraw $150,000 from an investment account to lend it to her campaign. you loaned money to your campaign, and then charged the campaign 18% interest? >> grace napolitano: that is correct. to be able to do a lot of the things i had to do were not feasible, unless i did what i had to do. and so at that point, that what was recommended, and that's what i went with. >> kroft: i don't think there's anything wrong with loaning your campaign money. but then collecting 18% interest from your campaign seems a little too much. >> napolitano: would you go out and get a loan and not get charged interest? >> kroft: it's still 18% and $228,000 in interest. >> napolitano: you like to favor 18%... >> kroft: i do like to favor. i mean, that's what the mafia gets. >> napolitano: it isn't like i've really profited. i still live in the same house. i drive a small car. i am not a billionaire, or a millionaire, for that matter. >> kroft: did your campaign contributors know that you were paying back a loan, charging the campaign committee 18%? >> napolitano: well, you don't go out and publicize that, but they know that i had a campaign

debt. >> sloan: when folks are asked for campaign donations and when they make campaign donations, they are doing it because they are in sync with that member of congress's views and they want to see them pushing policies and get reelected. i don't think they have any idea that some of that money is actually going into the member's personal bank account. >> kroft: there are currently two modest ethics reform bills pending in congress that would change a small part of what we've been talking about-- one sponsored by a senate republican, the other by a house democrat. neither has a prayer of even being debated. >> schweizer: we hear a lot about how there's so much partisan fighting in washington, steve. here's a great example of bipartisanship. both sides like this current system. >> welcome to the cbs sports update presented by pacific life. i'm james brown. the jets win in o.t. to move within one game of the patriots while dallas is now all along atop the n.f.c. east. the bengals win as time expires

>> gupta: dick cheney is one of the most polarizing figures in america. but whatever your opinion of him, you'll be surprised to learn that during his years in government, his biggest fight was for his own survival. he has been the beneficiary of nearly every medical breakthrough to combat heart disease over the last 35 years, including a heart transplant at the age of 71. and as you'll hear tonight, many of those innovations came just in time to save his life. it's all revealed in a new book called "heart" that he's written

with his cardiologist jonathan reiner. it's a medical story, but also a story about how his disease intersected with pivotal moments in modern history. cheney's health was so tied to his political career, just 67 days after taking the oath as vice president, he took a historic and unprecedented action. >> dick cheney: basically, what i did was i resigned the vice presidency, effective march 28 of 2001. >> gupta: so nearly for your entire time as vice president, there was a letter of resignation sitting there. >> cheney: pending. >> gupta: pending. >> gupta: cheney discovered there was no provision in the constitution to replace a vice president who is alive, but incapacitated. so he drew up a letter of resignation to give to the president. >> cheney: it says, "in accordance with section 20 of title three of the united states code, i, richard b. cheney, hereby resign the office of vice president of the united states." >> gupta: how did president bush react when you told him about this? >> cheney: a little surprised. but he thought it was a good idea.

>> gupta: it was just three years ago cheney says that people gasped when they saw how frail he had become. today, just 20 months after his heart transplant, cheney's weight is back to normal, the color has returned to his skin, he has no shortness of breath. how are you feeling? >> cheney: fantastic. now, i'm to the point where i literally, you know, feel like i have a new heart. a lot more energy than i had previously. there aren't any real physical limits on what i do. i fish, i hunt. and i don't ski, but that's because of my knees, not my heart. so, it's... it's been a miracle. dick cheney is a product of product of modern medicine at its best. he has suffered five heart attacks, undergone open heart surgery, multiple catheterizations and angioplasties, had a defibrillator implanted, and a pump attached directly to his heart -- all of that before his transplant at age 71. each time cheney reached the

precipice of death, a breakthrough in medical technology extended his life. bad hearts run in dick cheney's family, and early on, he did little to take care of himself. he had his first cigarette at age 12, and by the time he was president ford's chief of staff at age 34, his daily staples included fatty food, beer, and up to three packs a day. >> cheney: all the cigarette companies donated cigarettes in a white box with gold trim around it embossed with the presidential seal. that was kind of, if you were in a cocktail party or meeting in washington, and whipped out your presidential cigarettes and lit it up with a park of matches from air force one, that was sort of a status symbol. >> gupta: after his first white house stint, cheney returned to wyoming to run for congress. at just 37, his genetics and his lifestyle caught up with him. he suffered his first heart attack, and doctors thought he should quit the race, but he didn't want to hear it. you were pretty persuasive

because, i mean, they said, "it would be wise to drop out of this at the present time." >> cheney: they said that in the medical records. >> gupta: they didn't tell you that? >> cheney: well, i don't recall. what i took away from the conversations was that key phrase-- "hard work never killed anyone." >> gupta: patients like to hear what they want to hear. >> cheney: and that may well have been the case here, as well, too. but they also emphasized that stress comes from doing something you don't... don't want to be doing. >> gupta: he won that election, and five more after that, but his heart disease was steadily progressing. by the time cheney took over as the first president bush's secretary of defense in 1989, he'd suffered three heart attacks and undergone quadruple bypass surgery. it was a time of global upheaval. and dick cheney was in the center of it all-- the collapse of communism, the uprising in china's tiananmen square, and the first gulf war. >> cheney: our army, navy, air force and marines prepare for one of the largest land assaults of modern times.

>> gupta: looking back, do you think the stress affected your heart disease and your overall health? >> cheney: i simply don't buy the notion that it contributed to my heart disease. it was in fact that getting back to work, getting back to that job, whatever that job might be, was important enough that i, in fact, kept them separate, i guess would be the way to think about it. >> gupta: but i do wonder as a doctor, is that really plausible? can you really keep such a significant medical history and such a significant job separate? >> cheney: i did. >> gupta: but when george w. bush asked cheney to be his running mate in 2000, there was enough concern that the bush campaign sought out the opinion of world renowned texas heart surgeon denton cooley. after speaking with cheney's cardiologist, dr. jonathan reiner, dr. cooley told the bush campaign that cheney was in good health with normal cardiac function. the "normal cardiac function" wasn't true. >> cheney: i'm not responsible

for that. i didn't know what took place between the doctors. >> gupta: this idea that you have this respected heart surgeon from texas who didn't see you, didn't examine you, and then writes something saying that you have normal cardiac function. that just wasn't true, mr. vice president. >> cheney: go ask denton cooley about that. >> gupta: but sir, you saw it. >> cheney: listen to me-- i think the bottom line is, was i up to the task of being vice president? and there's no question. i think based upon the fact that i did it for eight years that they were right. >> gupta: how were they able to say that you were able to do the job? >> cheney: the way i look at it, sanjay, is that first of all, i didn't seek the job. the president came to me and asked me to be his vice president. the party nominated me. the doctors that consulted on it reached a common conclusion. and the people elected me. now, what basis do i override

the decision-making process? do you want to have an offshoot where we come check with sanjay gupta and say, "gee, is he up to the task?" that's not the way it works. >> gupta: despite cheney's insistence that he was fit for office, and just four months after being cleared by his doctors, cheney suffered another heart attack, his fourth. >> cheney: it was there and it was chest discomfort sufficient so i thought i ought to check it out. >> gupta: this time, it came while the country was embroiled in the 2000 presidential recount. cheney needed a stent to prop open a clogged artery. >> are you read to take the oath of office? >> cheney: i am. >> please raise your hand and repeat after me. >> gupta: yet again, modern medicine had helped dick cheney dodge a bullet. but it was just nine months later when cheney confronted what he considers one of the biggest challenges of his life, 9/11. with president bush in florida, cheney was in a bunker under the white house helping make decisions, even given authority by the president to shoot down passenger airliners.

i mean, as far as stress goes, and again, as a doctor, with your heart history, how worried were you about just your health in the midst of all this? >> cheney: didn't occur to me. >> gupta: not at all? >> cheney: no. i didn't think about my health. i was thinking about the problems we were dealing with. >> gupta: but what cheney didn't know was that his cardiologist, jonathan reiner, had received the results of a blood test that morning showing his potassium levels were dangerously high, a condition called hyperkalemia. big concern, i mean, how-- how big are we talking about? >> jonathan reiner: potassium of 6.9 can kill you. >> gupta: this is a huge problem. >> reiner: yeah. i laid awake that night, watching the replays of the towers come down and now thinking that, "oh great, the vice president's going to die tonight from hyperkalemia." >> gupta: another blood test the next day showed cheney's potassium levels were normal. but this level of scrutiny over dick cheney's health is a reminder he is not ordinary patient, and caring for him often required extraordinary precautions.

in 2007, when cheney needed his implanted defibrillator replaced, dr. reiner ordered the manufacturer to disable the wireless feature, fearing a terrorist could assassinate the vice president by sending a signal to the device, telling it to shock his heart into cardiac arrest. >> reiner: and it seemed to me to be a bad idea for the vice president of the united states to have a device that maybe somebody on a rope line or in the next hotel room or downstairs might be able to get into... hack into. and i worried that someone could kill you. >> gupta: it might sound farfetched, but years later, this scene from the showtime drama "homeland" showed just how it could be done to the fictional vice president. what did you think when you watched that? >> cheney: well, i was aware of the danger, if you will, that

existed, but i found it credible. because i know from the experience we'd had and the necessity for adjusting my own device that it was an accurate portrayal of what was possible. >> gupta: the precariousness of cheney's physical health raises questions about his state of mind when he was helping make decisions, including those about war and peace. you were instrumental in many big decisions for the country, including going into afghanistan and iraq. >> cheney: and terrorist surveillance programs and enhanced interrogation programs... >> gupta: terrorist surveillance programs, wiretapping, enhanced interrogation. you'd had four heart attacks, three catheterizations at this point, a defibrillator, bypass surgery. >> cheney: right. >> gupta: did you worry about your physical health impacting your judgment and your cognition? >> cheney: no. >> gupta: not at all? >> cheney: no. >> gupta: were you the best that you could be? >> cheney: you know, i was as good as i could be, you know,

given the fact i was 60-some years old at that point and a heart patient. >> gupta: cheney didn't want to acknowledge numerous studies that show a significant connection between severe heart disease and memory loss, depression, a decline in decision-making abilities, and impaired cognition. or that he could be one of the many patients vulnerable to these side effects. did they talk at all about potential side effects because of limited blood flow to the brain, on cognition, on judgment? was that something that you had heard about in any way? >> cheney: yeah. >> gupta: you didn't know about it? you weren't worried about it? >> cheney: no. >> gupta: both? did anyone counsel you at all on that? >> cheney: not that i recall. >> gupta: what about even things like depression? >> cheney: no. >> gupta: and that's all he wanted to say about that. but what dick cheney was eager to talk about was his transplant, detailed in his new book, "heart." >> cheney: when you emerge from, from that gift of life itself, there's this tremendous feeling of emotion, but it's very positive.

i think my first words when i came out from under the anesthetic when they said it had worked great was, "hot damn," literally. >> gupta: cheney and dr. reiner wanted to show us just how dramatic his transformation has been. this is an image of cheney's ravaged and diseased heart just moments after it was removed. >> reiner: this is a rather large basin. and here is the heart. >> cheney: it's the one i lived with for 70 years. >> reiner: a normal heart would basically be about the size of two fists clamped together like this, maybe even a little bit smaller. and you see this is about half a foot wide. >> gupta: old heart, new heart. >> cheney: old heart, new heart. its one of those situation where bigger is not necessarily better. >> gupta: that's because a bigger heart can't effectively pump blood through the body. the x-ray on the left shows cheney's enlarged heart, twice the normal size and pushing on his other organs. on the right, his new heart.

>> pelley: we very nearly lost one of the wonders of the world. the humpback whale was efficiently slaughtered until there were only a few thousand left. but in one of the great success stories in conservation, the humpback is making a comeback. it's a good thing, too, because what we've learned about them lately makes the humpback one of the most fascinating animals

ever to grace the earth. there are many species of whales, and one by one, they're coming off the endangered species list. whale hunting is rare today, but there is still a place on the high seas where there's a battle to eliminate the last vestiges of whaling. there, we found a man who has risked life and limb to end any threat to whales once and for all. you're watching the ramming of a japanese whaling ship by a combative conservation group led by american paul watson. he's trying to stop the transfer of a minke whale the japanese just killed to the factory ship that will cut it up. commercial whaling is banned by international agreements, but the japanese and a few others are still launching harpoons. these scenes were shot for the animal planet series "whale wars."

and these scenes were shot by the whalers themselves, who say this is evidence that watson is nothing more than a pirate. the japanese obtained an international arrest warrant for him. so, for the last year, this conservationist, or pirate, has lived on the world's oceans unable to set foot on land. we are headed out to international waters where watson lives on a ship beyond the reach of the law. but before he would meet with us, we had to agree that we wouldn't say where we are, or even what ocean this is. suffice to say it involved several airplanes and many thousands of miles. towards the end of that journey, watson sent this trimaran to pick us up. this boat once set the speed record for circumnavigating the earth. he named the boat for an actress who is a supporter, but to us, it looked more darth vader than

brigitte bardot. watson came to the "bardot" from a floating hideout that we agreed not to show. he is one of the founders of greenpeace. and now, at the age of 62, he calls his new armada sea shepherd. >> paul watson: the simple fact is this: if the oceans die, we die. sea shepherd was set up to uphold those international laws and regulations protecting our oceans. >> pelley: but why is that your job? countries enforce laws. why are you doing this? >> watson: i just do not see the political will on the part of these governments to do anything. >> pelley: but that makes you a vigilante. you're deciding on your own that you're going to enforce these laws. what gives you the right? >> watson: because i want to survive. and i want to make sure that my children survive. and i'm not going to sit back and watch the oceans be destroyed because governments don't have the political or economic will to uphold these laws. >> pelley: the whaling ban makes an exception for research.

and the japanese proclaim that exception in tall letters on their ships. they set their own quotas--about 900 minkes, 50 fin whales and 50 humpbacks. these are minkes. and even though the japanese reserve the right to kill humpbacks, they haven't, according to the international whaling commission. >> watson: there is no scientific basis for what they're doing. we have seen them take a whale onto the factory vessel. there's no scientist there. there's nobody measuring anything. they simply cut them up, send them down below, and package them. so, this is not science. it's bogus. >> pelley: the international court of justice in the hague will be deciding whether japan's whaling is really for research or should be stopped. but while the whaling continues, sea shepherd fouls the japanese plan with rope to catch their propellers. the japanese fire back with water, and ear-splitting sirens. sea shepherd throws stink bombs. the japanese return concussion grenades.

you called sea shepherd, which you founded, the most aggressive, no-nonsense conservation organization in the world. and you said, "i don't believe in protests. that is far too submissive." what do you mean? >> watson: well protesting is sort of like, "please, please, please, don't do that." but they'll do it anyway. but they just ignore you. so, protest is submissive. we're not a protest organization. we're an interventionist organization. we intervene against illegal activities. >> pelley: but this is what happened recently when sea shepherd tried to intervene. the whaler kept coming and sheared the bow off watson's $2 million boat, which eventually sank. no one was seriously hurt. watson claims he has cut the japanese catch because of these tactics; the same tactics that the japanese say are illegal. you're in sort of a prison, aren't you? >> watson: well it's a pretty

nice prison. it's... you know, i... i don't mind being on the ocean. it's a beautiful place, and certainly the citizens out here tend to be more peaceful. >> pelley: but when people call your tactics violent, how do you respond to that? i mean, you look as this footage, it looks violent. it's hostile. >> watson: the japanese are committing violence against living whales. we are not hurting anybody, so we're not violent. >> pelley: this battle is fought in the last place where humpback whales are considered endangered by the international agency that decides these things. these south pacific humpbacks feed here in the antarctic summer, then journey north 4,000 miles to mate. this is where much of the research is done, around a speck on the map called rarotonga. this volcanic island, part of the cook islands, is just 21 miles around with 10,000 residents and not a single

traffic light. here, we found the human who may know humpbacks best. >> nan hauser: he's right behind the boat. hello, beautiful. he's putting on quite a lovely show for us, and you just have to be careful and respect their space. >> pelley: they take up a lot of space. nan hauser is an american marine biologist who intended to come to rarotonga for one month of research, but that was 16 years ago. now, her home and lab are on the side of the volcano, and she spends her days eye to eye with her subjects. >> hauser: as you watch them, as you see these massive animals and look at them in the eye, and they're looking at you, and they've never seen what a human looks like before. and so they're curious about you, and you're curious about

them. >> pelley: humpbacks are acrobats. their fins are like wings up to 20 feet long. they cooperate with each other to hunt for the krill and small fish they eat by the tons. we've learned a lot about them in recent years, and some of what we know is because nan hauser has risked her life to discover it. she's part of an international mission to harpoon humpbacks with small satellite transmitters. that rubber boat feels tiny next to an animal 50 feet long that weighs 79,000 pounds. >> hauser: it's very, very dangerous. all they have to do is pick up their tail and give you a good whack, and all your bones are broken and your organs are ruptured. so it's very scary. very, very scary. my heart is pounding.

>> pelley: when they surface to breathe, the transmitter stuck in their blubber sends a signal. now, we know humpbacks can travel 10,000 miles a year-- that's the world record for a mammal. 80% of their lives are spent submerged. and this is where nan hauser has made some of her most beautiful discoveries. >> hauser: here, we see a male standing on his head, upside down, singing a song. they are motionless and the song bellows out. >> pelley: the humpback song can be 20 minutes long, and they repeat the same song again and again. males in one region will all sing the same song the same way. but next year, they'll return with a new composition. so, this is air somehow moving around inside their heads?

that's making this sound, even though they don't have vocal cords? >> hauser: correct. it's almost, i think, like taking a balloon full of air and going.... >> pelley: the sound carries for miles. and hauser believes, it's all to mark their territory. >> hauser: they take turns singing, perhaps to say, "my lungs are bigger. i can hold my breath longer. i can sing a more beautiful song. i'm the dominant male. i'm going to sing here so you move away and sing somewhere else. >> pelley: can you do some of the sounds that you've heard? >> hauser: i think the most common whale sound is kind of a... but we get everything. we've even had the laughing monkey-- "ee, ee, ee, ee." creaking doors. >> pelley: what are they saying? >> hauser: we don't know.

>> pelley: so you speak whale, but you don't understand it. >> hauser: absolutely. ( laughs ) >> pelley: but she does understand a calf's jaw-clapping anger. hauser captured it when a mother went off to mate and left this calf behind. >> hauser: he does a small clap. right here. >> pelley: what does it mean? >> hauser: now, i know it means, "i'm upset and i'm going to have a little bit of a temper tantrum." you can see him. hear him? >> pelley: he's saying, "pay attention to me." >> hauser: exactly. >> pelley: humpbacks give birth to one calf a year. so their comeback has been slow but steady. before the whaling ban, there were maybe 5,000 left in the world. but now, it's estimated there are 80,000. the biggest threats to them these days are collisions with ships, and the kind of miles- long fishing line that wrapped up this whale. >> hauser: they get wrapped up, and then they get held underwater and they need to come up for air.

otherwise, they suffer and they drown. >> pelley: hauser hopes that the satellite tags will mark migration routes so that man can steer clear. history may show that we stopped the global slaughter just in the nick of time. humpbacks are now found in every ocean. their numbers back to about 30% of what they had been before whaling. it's a sign that a fascinating and beautiful part of the planet is on the mend. ♪ [ male announcer ] when we built the cadillac ats from the ground up to be the world's best sport sedan... ♪ ...people noticed. ♪
